Product Description

Our Power Capacitor Products plant located in Greenwood, South Carolina, manufacturers McGraw-Edison high voltage power capacitors for worldwide utility and industrial applications for system voltages from 2.4 kV through EHV. Cooper Power Systems produces capacitor subsystems for shunt, series, HVDC, SVC, and filtering applications throughout the world.

The Type EX-7L capacitor, introduced by Cooper Power Systems in 1990, and the Type EX-D capacitor, introduced by Cooper Power Systems in 1995, are the most technologically advanced capacitors available today.

Standard Cooper Power Systems' factory assembled capacitor blocks consist of distribution-class capacitors connected in parallel, series- parallel, or in a three-phase arrangement and mounted in a sturdy welded aluminum frame. The individual capacitor units are rated 100, 150, and 200 kvar, 2400 to 21600 volts, and at 75, 95, and 125 BIL. Blocks are also supplied with properly sized, bus-mounted, indicating-type fuses for individual capacitors

As you would expect from the leading supplier of high voltage capacitors, Cooper offers an unexcelled range of capacitor bank protection relays. Most protection schemes are in the form of add-in software modules for the or relays, members of the Edison? /sup> Idea line of relays. These modules use the feature of the Idea platform whereby new functions and features may be uploaded to standard relays, thereby reducing the number of models to manage. Custom Capacitor Bank Protection Schemes

The Idea Workbench feature also permits Cooper to develop unique capacitor bank protection and control schemes specific to your unique requirements. For more information on a custom protection scheme, contact your local Cooper Power Systems representative or us.

Edison IM30CE Capacitor Bank Relay

The IM30CE is a neutral current unbalance relay ideal for the protection of double wye connected and grounded wye capacitor banks equipped with neutral CTs.

The IM30CE offers inherent bank unbalance compensation, two levels of unbalance detection, capacitor bank reclosing time delay logic, and three-phase and ground overcurrent protection. In addition, a separate low set RMS sensing phase overcurrent element is provided for.

Instruction Manual S150-60-1 Edison IM30CV Capacitor Bank Relay

The IM30CV is a neutral unbalance relay suitable for the protection of ungrounded single or double wye connected capacitor banks equipped with a neutral voltage transformer.

The IM30CV offers the other features as the IM30CE relay above.

ICP-440 Capacitor Bank Protection Relay

The iCP-440 capacitor bank protection relay is a full-featured Edison® IdeaTM relay suitable for shunt capacitor or filter bank protection and automatic voltage control applications. The relay is ideally suited for new or retrofit applications of fuseless or internal/externally fused banks requiring neutral unbalance protection. It utilizes voltage or current neutral unbalance to provide flexible protection for both grounded and ungrounded banks. Single or double wye bank configurations may be accommodated. The relay easily permits nulling of inherent bank unbalance and compensates for real time system unbalances (single wye) thus permitting maximum sensitivity for detection of internal problems. The relay detects capacitor unit failure when the compensated neutral quantity increases beyond a threshold. The neutral unbalance algorithms permit secure and economical protection on banks of various var ratings. The iCP-440 also provides advanced power quality, metering, communication, and PLC functions
